CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:HSummary
CVE-2024-27804 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Apple Visionos. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Denial of Service (T1498); ranked in the top 32% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and SC-6 (Resource Availability) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-27804 is a memory-handling flaw affecting multiple Apple operating systems, including iOS and iPadOS prior to 17.5, macOS Sonoma prior to 14.5, tvOS prior to 17.5, visionOS prior to 1.3, and watchOS prior to 10.5. The vulnerability stems from insufficient controls on resource allocation and sequential memory operations, classified under CWE-770 and CWE-1325, and carries a CVSS 5.5 rating reflecting local attack vector, low complexity, and high availability impact without requiring elevated privileges.
An unprivileged local application can trigger the flaw after user interaction, leading to unexpected system termination and a denial-of-service condition on the affected device. No remote code execution or data compromise vectors are indicated in the available details.
Apple security advisories for the listed platform updates state that the issue was resolved through improved memory handling in the released versions, with installation of iOS 17.5, macOS Sonoma 14.5, and equivalent updates serving as the primary mitigation.
EPSS scores remained low throughout, reaching a modest peak of 0.0636 before receding to the current 0.0427, indicating limited post-disclosure exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces a hard limit on concurrent sessions, structurally preventing unbounded resource allocation.
SC-6 directly enforces resource quotas and priority allocations that stop unbounded sequential memory requests from exhausting the system.
Imposes a limit on consecutive invalid attempts, preventing one specific class of unbounded resource consumption.
Reduces impact of resulting DoS events without preventing the underlying lack of allocation limits.

Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.
Security testing can detect unbounded allocation patterns, but removing the weakness does not fulfill testing obligations.
Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.
Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.
Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.
Secure development life cycle includes resource-management requirements that can prevent uncontrolled per-object allocations.
